Instead of moving a single component, you should group the components that should remain static, and then move them as a group.

In your example, I'm assuming you moved the R-Pi down. Instead, you could group the R-Pi and also the three wire vertices (corners) to its upper left (a total of 4 objects). Then move them as a group down. The wires coming out of the R-Pi would then stay at a right angle and the 3 vertical wires would adjust in height.

Alternatively, after you move the R-Pi as in your picture, you could group the 3 wire vertices and move them into position as a group. There's no need to move them individually.
